Abstract
The utility model discloses a grounding wire protective sleeve, and pertains to the technical field of ground wires. The grounding wire protective sleeve comprises a ground wire hook provided with a first wire nose connection plate and a metal wire, and further comprises a first spring sleeve. The first spring sleeve sleeves the left end portion of the metal wire and used to make the left end of the metal wire exposed. The left end of the metal wire is connected with the first wire nose connection plate. According to the utility model, the spring sleeve sleeves the insulating layer of the metal wire, so the strength and the elasticity of the end portion of the metal wire of the grounding wire can be increased, and during utilization, the bending, strand breaking and abrading of the metal wire of the grounding wire caused by repeated dragging can be avoided, the sectional area of the metal wire will not be reduced, the conductivity will not be reduced, the service life of the grounding wire can be prolonged, the safety production can be ensured, and the repair working efficiency can be improved.
Description
Technical field
The utility model relates to earth connection technical field.
Background technology
In transmission facility service work, most important safety measure is installing earth connection, and before maintenance starts, transmission facility has a power failure and ground wire is installed, and maintenance finishes to dismantle ground wire.Using qualified earth connection is that the safety that guarantees the person and equipment is wanted one of measure most, in upkeep operation, ground wire is used frequent, in ground wire junction, because repeatedly pull firmly use angle, change, or frequent bending makes its insulation sheath breaking releasing, often cause the copper conductor of earth connection outside exposed, further make copper conductor wearing and tearing and cause disconnected strand, the copper conductor sectional area that forms earth connection reduces, and becomes the potential safety hazard in service work.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of earth connection protective sleeve, has disconnected strand of plain conductor wearing and tearing that prevent earth connection, extends earth connection useful life, guarantees the feature of safety in production.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of earth connection protective sleeve, comprises the ground wire hook and the plain conductor that are provided with First Line nose connecting plate; Also comprise the first spring protecting sleeve, described the first spring protecting sleeve is sleeved on the left part of plain conductor and the left end head of plain conductor is exposed, and the left end head of plain conductor is connected with First Line nose connecting plate.
The further improvement that the utility model is made is: also comprise the second spring protecting sleeve, the second line nose connecting plate and ground wire band iron; Described the second spring protecting sleeve is sleeved on plain conductor right part and the right-hand member head of plain conductor is exposed, and the right-hand member head of plain conductor is connected with the second line nose connecting plate, and described ground wire band iron is connected with the second line nose connecting plate.Described the first spring protecting sleeve and the second spring protecting sleeve roll by spring steel wire and are locked in the insulating barrier outside of plain conductor.
The beneficial effect that adopts technique scheme to produce is: spring protecting sleeve of the present utility model is sleeved on the insulating barrier outside of plain conductor, end intensity and the elasticity of the plain conductor of earth connection have been increased, in use, can avoid the plain conductor of earth connection to produce disconnected burst of wearing and tearing of bending because repeatedly pulling, the sectional area that guarantees plain conductor does not reduce, and conductive capability does not reduce, and extends earth connection useful life, guarantee safety in production, improve service work efficiency.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
As shown in the figure: 1 ground wire hook, 2 joint sleeves, 3 ground wire insulating rods, 4 First Line nose connecting plates, 5 first spring protecting sleeves, 6 plain conductors, 7 second spring protecting sleeves, 8 second line nose connecting plates, 9 ground wire band irons.
Embodiment
Contrast Fig. 1 is used step to be described further to operation of the present utility model:
Embodiment 1: a kind of earth connection protective sleeve, comprises the ground wire hook 1 and the plain conductor 6 that are provided with First Line nose connecting plate 4; Also comprise the first spring protecting sleeve 5, described the first spring protecting sleeve 5 is sleeved on the left part of plain conductor 6 and the left end head of plain conductor 6 is exposed, and the left end head of plain conductor 6 is connected with First Line nose connecting plate 4.Also comprise the second spring protecting sleeve 7, the second line nose connecting plate 8 and ground wire band iron 9; Described the second spring protecting sleeve 7 is sleeved on plain conductor 6 right parts and the right-hand member head of plain conductor 6 is exposed, and the right-hand member head of plain conductor 6 is connected with the second line nose connecting plate 8, and described ground wire band iron 9 is connected with the second line nose connecting plate 8.Using method: the first spring protecting sleeve 5 and the second spring protecting sleeve 7 all do not stay burr wedge angle at two ends sanding and polishing, and length is 8cm, and external diameter is respectively 10mm, 12mm and 14mm.Be used for the plain conductor 6 of ground connection and match, internal diameter is slightly less than the diameter of plain conductor 6 periphery insulating cases.By being installed, the first spring protecting sleeve 5 and the second spring protecting sleeve 7 avoided plain conductor 6 two ends to kill curved situation, and protected plain conductor 6 to produce because of wearing and tearing disconnected strand, thus guaranteed the person, the device security of operation field.
Embodiment 2: a kind of earth connection protective sleeve, comprises the ground wire hook 1 and the plain conductor 6 that are provided with First Line nose connecting plate 4; Also comprise the first spring protecting sleeve 5, described the first spring protecting sleeve 5 is sleeved on the left part of plain conductor 6 and the left end head of plain conductor 6 is exposed, and the left end head of plain conductor 6 is connected with First Line nose connecting plate 4.Also comprise the second spring protecting sleeve 7, the second line nose connecting plate 8 and ground wire band iron 9; Described the second spring protecting sleeve 7 is sleeved on plain conductor 6 right parts and the right-hand member head of plain conductor 6 is exposed, and the right-hand member head of plain conductor 6 is connected with the second line nose connecting plate 8, and described ground wire band iron 9 is connected with the second line nose connecting plate 8.Described the first spring protecting sleeve 5 and the second spring protecting sleeve 7 roll by spring steel wire and are locked in the insulating barrier outside of plain conductor 6.The using method of the present embodiment is identical with embodiment 1.
